Android 10上動用相機和圖庫 並且返回裁剪圖片遇到的問題 記錄一下：各種報錯，
1.exposed beyond app through Intent.getData()
2.java.lang.IllegalArgumentException: URI is not absolute
3.android.os.FileUriExposedException: file:///storage/emulated/0
4.exposed beyond app through ClipData.Item.getUri()
網上找了一大圈，報錯原因 大概如下 ，動態權限沒有申請， Android N（對應sdk24）（版本7.0）及以上對訪問文件權限收回，還有其他之類的錯誤原因，直接上代碼 ，在Android 10 ,Android 8.1,Android5.1真機上已驗證ok
AndroidManifest.xml新增 code
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="test.xxx.com.myapplication.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
file_paths文件 path=".",我的理解是Environment.getExternalStorageDirectory()所在的目錄，name可以任意取
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="images"
path="."/>
</paths>
